在新型城镇化背景下对绿地经济发展状况进行研究,以江苏省为例,构建了评价指标体系并通过熵权法计算各区域绿地-经济发展模型的综合分数,利用K-Means方法进行空间聚类,最后基于空间计量分析进一步探究综合分数在空间和时间上的滞后效应... 在新型城镇化背景下对绿地经济发展状况进行研究,以江苏省为例,构建了评价指标体系并通过熵权法计算各区域绿地-经济发展模型的综合分数,利用K-Means方法进行空间聚类,最后基于空间计量分析进一步探究综合分数在空间和时间上的滞后效应和相关性,研究表明:(1)人均GDP和人均公园绿地面积的增大能够提升第三产业在GDP中的比重,且三者能够显著拉升绿地经济发展模型的综合分数;(2)城镇居民可支配收入对综合分数的贡献度很低,江苏省主要通过传统重工业来提高民生经济,这不利于绿地建设;(3)绿地经济建设发展具有一定的时间和空间滞后性,前者主要来自以核心城市为中心的产业圈辐射时间差,后者则由苏南到苏北在发展程度逐渐降低、边际向内部逐渐降低的滞后效应。 展开更多

指出了上杭绿地建设在短时间内取得优异成效的同时,也发现其在绿地建设过程中存在的不少问题,尤其是在近来生态文明大背景下,城市绿地建设相比其他先进园林城市建设显得较为滞后,且其绿地效果已不能满足人民日益增长的优美生态环境需要... 指出了上杭绿地建设在短时间内取得优异成效的同时,也发现其在绿地建设过程中存在的不少问题,尤其是在近来生态文明大背景下,城市绿地建设相比其他先进园林城市建设显得较为滞后,且其绿地效果已不能满足人民日益增长的优美生态环境需要。鉴于此,以上杭县城绿地建设为研究对象,通过上杭县城绿地建设实际情况分析和相关理论研究,分析了上杭绿地建设过程中存在的问题,在借鉴目前我国城市绿地建设中的先进经验基础上提出了合理有效的治理措施,以期进一步提升上杭县城绿地建设水平和能力,推动上杭县城的绿地发展、构建完整的绿地系统。 展开更多

Fenlong green ecological agriculture technology (Fenlong technology), a new smash ridging farming method developed by Guangxi Academy of Agdcultural Sciences, has been elected as the recommended cultivation technique by the Ministry of Agriculture of China. It replaces the traditional plowshare with spiral drill, and its tilth depth is twice deeper than that by tractor tilthing. It also extends soil nutrient, moisture, oxygen and microorganism, the so-called "Four pools". Soil nutrient, oxygen, microorganism, light and rainfall use ratio is increased by 10%-100%, creating a platform for natural increase of more than 10% of crop yield. Its application to over 20 kinds of crops in 21 provinces has proved that the yield increases 10-30% with quality enhancing 5% and double water retaining capacity but no more input. When the application area of Fenlong could reach 67 million hm2, the amount of fertilizer can be reduced by 40-50 billion kg, saving 120-150 billion Yuan. In this paper, we put forward the strategy of "4+1" (arable, saline-alkali soil, grasslands, Sponge City + rivers) green development in China, and deepened the Fenlong cultivated tilled layer from 16.5 cm to 35 cm for 67 million hm2 arable land, ridged 13.3 million hm2 of saline-alkali soil for 35 cm, and also 35 cm for 67 million hm2 degraded steppe, which could have the following 3 effects: first, the 147 million hm2 of land with Fenlong cultivation could increase loosing soil to 315.491 billion m3, in* creasing by 159.26% for 120 million hm2 of arable land with the average tilled layer of 16.5 cm, which has loosing soil of only 198.1 billion m3, that is, the space of the land increases 1.6 times. Second, every hectare of plowland could store up to 450 m3/hm2 of natural rainfall, and the unused 60 m3 of saline-alkali soil and grasslands could store water of 102 billion m3, showing an increase of over 88.89% for the current plowland storage of 54 billion m3 at now, that is, double the natural rainfall storage capacity. Third, the two multiple increase of natural resources application can bring trillions of resource activation, environmental cleaning, food security, citizens, health, economic, ecological and social benefits, and makes the Chinese nation move forward in green development. Its application in "big scientific research" and "One Belt And One Road" will contribute Chinese strength to the world. 展开更多

The paper researches on the pattern of man-land relationship of artificial oasis in the east of north Tian-shan Mountain,the development of Qitai artificial oasis and its relationship with envirorvnet.analyzes the facors influencing the change of Qitai artificiul oasis and its relationship with envirorunent,analyzes the factors influencing the change of Qitai artificial oasis and economic growth through grey analysis,and suggests the approaches of sustainable development of Qitai artificial oasis.Research shows that the pattern of artificial oasis and its environment had gone through three phases:the relatively harmonious stage.the unharmonious stage,and the new fragile balance stage.It also shows that the garden and the shelter-forest are useful to the sustainable development of Qitai oasis according to grey analysis. 展开更多
